Download or read book Ejectors for Efficient Refrigeration written by Giuseppe Grazzini and published by Springer. This book was released on 2018-03-21 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Encompassing both practical applications and recent research developments, this book takes the reader from fundamental physics, through cutting-edge new designs of ejectors for refrigeration. The authors’ unique vision marries successful design, system optimization, and operation experience with insights on the application of cutting-edge Computational Fluid Dynamics (CFD) models. This robust treatment leads the way forward in developing improved ejector technologies. The book covers ejectors used for heat powered refrigeration and for expansion work recovery in compression refrigerators, with special emphasis on two-phase flows of “natural” fluids within the ejector, i.e. steam and carbon dioxide. It features worked examples, detailed research results, and analysis tools.

This book was released on 1965 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: The turbulent mixing region of a two-dimensional, supersonic, air-air ejector system was experimentally investigated utilizing an interferometer. Density distributions for the two-stream mixing region within the ejector duct were established for 6 different test configurations. Similarity of the density distributions was indicated for mixing region cross sections as close as one nozzleexit hydraulic diameter from the nozzle. Density profiles at successive downstream duct locations were plotted to show the spread of the mixing region. The effect of normal and oblique shocks on the rate of spread of the mixing region was found to be small. In addition, ejector performance data and techniques for spark lamp photography are presented. It is concluded that the interferometer could be effectively utilized to help determine the transport coefficients of ejector system turbulent mixing processes. (Author).

Book excerpt: The capability of producing additional thrust along with the ability of vectoring the thrust makes the ejector an attractive device for V/STOL aircraft applications. In addition, the acoustic shielding provided by the walls of the shroud, and lowered exhaust velocities and temperatures at the ejector exit offer important advantages in the area of nozzle exhaust cooling. One of the physical processes which is known to play a large role on the performance of the total system is the mixing between the hot primary and cold secondary streams. Thus an attempt is made here to investigate the mixing process of a hot rectangular jet with an entrained cold ambient fluid in a simple form of a ejector. Primary jet heating, over the temperature range tested, has no significant effect on the velocity field within the ejector shroud. The temperature decay within the ejector shroud displayed differences in comparison with the free jet up to a location where the primary jet spreads to the mixing duct wall. Downstream of this location the centerline temperature within the ejector is higher than that of a free jet. A theoretical analysis is made to set up a determinate mathematical problem for the flow through a constant area ejector. It is shown that multiple solution (more than two) occur, and admissible ones out of these are those that fulfill the entropy condition.

Available in PDF, EPUB and Kindle. Book excerpt: Mixing of two streams of compressible fluid having arbitrary properties at the start of mixing results in one of two possible states upon conclusion of the mixing process. These two final states can be differentiated by the fact that the Mach Number of the fully mixed flows are related in the same manner as are the Mach Numbers across a normal shock wave. One of these states is always representative of a subsonic flow and the other a supersonic flow. Since both solutions represent flows which satisfy the laws of mass flow and energy conservation and the momentum theorum in a channel of uniform cross-section, the physical possibility of achieving these end states must be corroborated by examination of the process in terms of the Second Law of Thermodynamics. Therefore the total entropy change of the flows from the initial to the final state have been determined. It is shown that both solutions correspond to flows which have a positive entropy change in certain ranges of the initial conditions while in other ranges the solution corresponding to a supersonic end state may violate the Second Law of Thermodynamics. Applications of these solutions to the flow through an ejector provide a means for design optimization which results in high thrust augmentating capability at any given flight speed. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation was performed to study the characteristics of the flow in a two-dimensional air ejector in which the center stream entered the mixing chamber at a Mach number of 1.90 while the velocity of the secondary flow was varied from zero to Mach 0.7. Mass flow ratios of the ejector were approximately equal when the pressures of the two streams were equal at the entrance to the mixing chamber. The chamber had a rectangular cross section and converged slightly; its length was equal to 16 times the width. Pressures measured at the walls and the centerline of the flow indicated that a maximum static pressure was reached at 8 widths of the chamber downstream of the nozzle when the flow was completely expanded at the nozzle exit. The maximum static pressure was achieved in less distance for the overexpanded condition and took longer for the underexpanded condition. The flow was always subsonic by the time the maximum pressure position was reached except in the underexpanded case, where the flow remained supersonic throughout the chamber and the maximum pressure was located at the exit to the chamber.
